Description
xThe NZ2VZ-538E is a slow-action safety switch with a separate actuator, featuring two positively driven contacts and connection via an SR6 plug connector (6-pin plus PE). It is rated at 4 A for AC15 and DC13 duty (derated to 2 A above 70°C), with a degree of protection of IP65 and an ambient temperature range of -25 to +80°C. The housing is anodised die-cast alloy with silver alloy, gold-flashed contacts, suitable for use on guarded machine access points where door position monitoring is required. Actuation is direction-dependent and can be changed, with an approach speed of up to 20 m/min and an actuation frequency of up to 1200 operations per hour.
